If it is true -- as argued in the book Gold Warriors (a must read) that much, maybe most, of the gold in the world is off the books, that is, does not officially exist, then there is a real chance that the financial elite will -- at some point -- dump large amounts of gold onto the market -- to drive the price down.

It would be risky for them to do it --

There would be a lot of angry investors -- and probably new lawsuits -- about where the gold came from. However, a similar thing happened in the 1990s.
